I discovered a hack deal by just pouring extra shots of espresso into the coffee. One cup, 10 shots, one gram of caffeine. Expect the barista to glare with concern, it’s part of the deal.

I did once have two quad espressi while waiting for a flight at stupid o'clock in the morning at Stansted airport. The guys in Costa coffee mostly just found it amusing.

I was also once approached by an alcoholic who chastised me for drinking coffee in a bar in the middle of the day instead of "a real drink". I offered to take a shot of vodka for each espresso he drank and "we would see who dies first". He didn't take me up on my offer.
